This invention relates to a sash guide and seal, and particularly to a. sash guide and seal for a pair of relatively slidable-window sash.

An object of the invention is to provide an im- 5 proved sash guide formed of sheet metal which is adapted to be secured to a window frame to provide guideways or grooves in which the sash may slide without binding.

Another object of the invention is to provide 10 a sash guide of the foregoing character having, in addition to the grooves for permitting the free sliding movement of the sash,.means for sealing the sash and window frame to prevent the passage of air or moisture.

A further object of the invention is to provide a two-part metal sash guidev provided with a parting stop located between the sash grooves.

Another object of the invention is to provide a two-part metal sash guide provided with a 20 composite wood and metal parting stop.

A further object of the invention is to provide a metal sash guide formed of two parts adapted to be assembled together in edgewise relation to provide a substantially centrally located parting 25 stop inwhich each of the sections is provided with a sash groove having a weather strip located therein.

A further object of the invention is to provide a sash guide or a combined sash guide and 30 weather seal composed of two separate and independent parts capable of being produced in a single rolling machine or by a stamping process; and one which is of relatively simple construction,

. inexpensive to manufacture and capable of quick 35 assembly and installation. The above and other objects of the invention will'appear from the following description and.

appended claims when considered in connection with the accompanying drawing forming a part 40 of "this specification.

In said drawing:

Fig. 1 is an inside elevation of a window and frame showing in broken lines, one form of sash guides embodying the present invention.

Fig. 2 is a fragmentary horizontal section, on an enlarged scale, taken substantially along the line 2-2 of Fig. 1.

Fig. 3 is a fragmentary perspective view of the sash guide of Fig. 2.

" Fig. 4 is a fragmentary horizontal section, on an enlarged scale, showing a combined two-part sash guide and seal and associated parts embodying the invention; and

Fig. 5 is a view similar to Figs. 2 and i showing a modified form of sash guide and parting stop, embodying the invention.

Before explaining in detail the present invention it is to be understood that the invention is not limited in its application to the detailsof' construction and arrangement of parts illustrated in the accompanying drawing, since the invention is capable of other embodiments and of being practiced or carried out in various ways. Also it is to be understood that the phraseology or terminology employed herein is for the'purpose of description and not of limitation, and it is not intended to limit the invention claimed herein beyond the requirements of the prior art.

Referring particularly to Figs. 1 to 3 inclusive, there is shown one form of sash guide embodying the present invention. As shown, the sash guide is formed in two parts or sections A and 2B, the section or strip A having a depressed portion-or sash groove l0 and the section or portion B having a. sash groove II. The section A is provided with a weather strip member or rib I 2 and is flanged at its inner longitudinal edge to'provide one portion l3 of a parting stop or spacer member C. The outer edge of the strip I0 is inwardly flanged at It for a purpose to be hereinafter described. The section or portion B of the guide has a weather strip or rib l5 similar to the rib I2 and the inner free edge of said section is flanged at IE to provide the second half or portion of the centrally disposed parting stop C. The outer edge of the section B is inwardly flanged at 11 similarly to the flanged edge H of section A. It will be noted that the parting stop portions or halves I3 and 16 are provided, respectively, with interfitting or nested portions or members which serve to lock the parts together when the two sections are assembled in edgewise relation. The parting stop portion I3 is formed with-a longitudinally extending channel or groove l8 adapted to receive a longitudinal rib or projection l9 formed in the stop portion IS. The upper sash 20 is provided with a saw cut or kerf to receive the weather strip rib I2 and the lower sash 2| is provided with a similar saw cut or kerf to receive the weather strip or rib IS, the saw cuts being preferably slightly larger than the weather strips so as to insure the freedom of relative movement of the sash and strips.

The sections A and B of the sash guide are assembled with their respective sash and the inner faces or walls of the parting stop portions" or members l3 and I6 are brought into edgewise abutting relation, whereupon the whole assembly is slipped into the trackway or recess formed in the window frame. When assembled the base of the sash guide sections lies flat against the window frame member 22 with the flange l4 engaging the blind stop 26. The inner window stop 24 is secured in place with relation to the window frame member 22 and when in place, the inner edge of the stop 24 engages the outer face of the flange II. The metal guide sections A and B are preferably secured in place upon the window frame member 22 by means of nails or screws (not shown) which may be passed through preformed holes in the "base portions l0 and II of the guide. When the parts are assembled as above described, it will be seen that each sash is located in and engages the sash groove formed in its respective guide member, the inner edge of each sash abutting the adjacent flange of the parting stop section or portion. The outer edge of each sash is in contact with the metal edge flanges M or ll of the sections A and B, respectively.

By virtue of the above described construction it is possible to first assemble the section A of the guide with its sash 20 and insert the assembly in the window frame, and threafter assemble the guide portion B with the lower sash 2| and then insert these assembled parts in the window frame. The present construction permits of the above method of assembly and materially reduces the time factor in assembling the window sash with the window frame. With previous forms of sash guide structures it has been necessary to assemble the sash guide with both sash and to then insert the entire assembly into the window frame.

Referring particularly to Fig. 4 there is shown another embodiment of the present invention in which the sash guide of the preceding figures is modified to include sealing means for the window and frame. In this form of the invention the base portions l6 and II of the guide sections or strips A and B, respectively, the Weatherstrip ribs l2 and I5 and the separable parting stop members or portions l3 and i6 are identical with these parts shown in the preceding views. The outer edge flange H of section A, however, is different, as is the edge flange H of section B. In lieu of the single flanges i4 and I! of the preceding form, the metal at the outer longitudinal edge of guide section A is reversely or return bent at substantially a right angle to the base ill to provide a substantially U-shaped or double flange, while the metal at the outer edge of section B is similarly reversely bent to provide a double or U-shaped flange 26. The outer leg of flange 25 is bent outwardly at right angles to provide a longitudinally extending sealing strip vor member 21 and the outer leg of the flange 26 is similarly bent outwardly at right angles to provide an extension or longitudinally extending sealing member or portion 28. It will be seen that the sealing strips or portions 21 and 26 extend outwardly in substantially the plane of .the base portions in and ii.

When the sections A and B are assembled together and with the upper and lower sash 20 and 2|, these assembled parts are inserted in position against the window frame member 22, the guide sections A and B being secured in place in any suitable manner, as by means of nails or screws passing through the metal of the guide sections. The blind stop 23 has a saw cut or kerf formed therein to receive the sealing flange 21 and the inner window stop 24 has a cut-away portion to receive the sealing flange 28 so that when the member 24 is attached to the frame member 22, the flange 26 is clamped; between these two members. vIt is to be noted that the LI-shaped flanges 25 and 26 are located, respectively, be-

tween the blind stop 23 and the back "or outer face of the sash 20 and the inner window stop 24 and the front or inner face of the sash 2|. Thus the sections or halves l3 and i6 of the parting stop provide guides for the adjacent inner faces of the upper and lower sash 26 and 2| and Referring particularly to Fig. 5., a further embodiment of the present invention is shown. In this form, the frame member 22 has applied to its inner face a centrally disposed wood block or parting stop 29 having in its outer face a sub stantially centrally disposed longitudinal saw cut or groove to receive the parallel inner flanges I3a and l6a of the metal parting stop members or portions l3 and I6, respectively. In all other respects the sash guide of Fig. 5 corresponds to the form shown in Figs. 1 to 3 inclusive. method of assembly of this form may be substantially as follows: The section A of the sash guide is first applied to the face of the frame member 22 with its outer longitudinal flange I4 engaging the inner face of the blind stop 23, it being understood that the section A is first applied to the upright edge or face of the upper sash 26. When the assembled sash guide A and sash 20 are ap-- plied to the window frame, the parting stop section l3 engages the wood parting stop 29 with the flange l3a thereof resting within the saw cut formed therein. The section B of the guide is now applied to the lower sash 2|. and the assembled parts slipped into position against the inner face of the window frame member 22,. thc half or section I6 of the metal parting stop en-- gaging the wood stop 29 and the flange [6a of said metal stop portion fltting within the groove or saw cut formed in the wood stop member. After the upper and lower sash and sash guide sections have been installed as described the inner window stop 24 is then secured to the face of the frame member 22 in which position the flange l'l contacts the inner edge or face of the member 24. form of Figs. 1 to 3, the longitudinal outer edge flanges l4 and I! extend inwardly from the base portions of the guide at an angle slightly less than a right angle. Thus, when the guide parts A and B are installed in the window frame, they are held under compression due to the flexibility of these flanges. By virtue of the presentv form of the invention the sash 20 and 2i also .have,

invention shown in Fig. 5 may be modified in' The i It will be noted that as in the case of the .iis

sash grooves, the free accordance with the structure shown in Fig. 4 without departing from the spirit of the present invention, so that the guideof Fig. 5 will include a weather seal or seals.
